Now LG has an offer that sweetens the arrangement further. If you purchase a new G4 or V10 by Christmas Day and register online before January 8th, you will receive a $100 prepaid card in the mail.

If you throw in the potential $300 you can get from trading in an existing device, you're looking at effectively saving $500 altogether on a V10. Kind of. You have to spend the $100 before you get it back.

Still, who doesn't like receiving $100 so long after a purchase that it feels like a surprise gift? Happy holidays.
